To all whom, 'it may concern:

Be it known that I, NIoHrrU V. GHETIA, a citizen of the United States, residing at Cleveland in the county of Cuyahoga and State of Oliio, have invented certain new and useful Improvements in Hair Clippers, of which the following is a specification, reference being had to the accompanying draw- 1n s.

his invention relates to hair clippers, and oneof the principal objects of the invention is to provide a portable outfit including a clipper which may be operated electrically through a source of power carried inthe outfit or through an outside source, as is found most desirable, and which at the will of the operator may be converted into a manuall operated clipper.

Clippers have heretofore been devised which were adapted to be converted from electrically operated cli pers to manually operated clippers, but tiie mechanism was so complicated that they were not effective for any length of time. It is therefore the object of this invention to simplify the construction of these present clippers and to provide simple and efficient means whereby the clipper may be converted from a power` operated clipper to a manually operated one.

A further object of the invention is the provision of novel means for mounting a manual operating handle in such manner that it may be utilized to operate an electrical switch when thrown out of manual operating position and will lie out of the path of the switch when in manual operating` position.

urther objects of the invention will appear as the following specific description is read in connection with the accompanying drawings which form a part of this application and in which:

Figure 1 is a top plan view of a clipper outfit with the cover removed so as to show the relative position of the parts therein;

Figure 2 is a top plan view of the clipper` showing parts arranged for power operation;

Figure 3 is a similar view showing the parts arranged for manual o peration;

Figure 4 is a perspective view of the manual operating lever removed;

Figure 5 is a section taken on the line 5 5 of Fig. 3;

Figure 6 is a section taken on therline 6-6 of Fig. 3;

Figure 7 is a mounting pin. i Referring more particularly to the draw ings, 1 represents a stationary cutter plate which has connected to the same and extendlng rearwardly therefrom a casing plate 2 provided with laterally extending flanges 3 and 4 which are en ged by the cover 5 when in position. This plate 2 and its associated flanges and top are preferably made of some non-magnetic material, and mounted upon, and insulated from the flange 3 by means of the strip of insulation 6, arethe electro-magnets 7 arranged for actuation of the power operating lever 8`to be hereinafter described.

Mounted upon the stationary cutter plate 1 is a removable cutter plate 9 having slots 10 to receive the headed guide pins 11 which guide the reci rocation of the plate as is understood. e movable plate 9 is provided with a centrall arranged notch 12 which is engaged by t e forward extension 13 of the operating lever, and which forward extension is normally held in one position by a helical-spring 14 secured to the plate 1. The operating lever is mounted upon a pivot pin 15 "arising from the plate 2, which pin, as is shown in` Figure 7, is provided with a head 16 and a rounded shank 17. Intermediatel thevshank 17 and the head 16 the pin is reduced on diametrically op posite sides, as indicated at 18, and mounted upon the reduced portion is the manual operating lever 19 provided with an elongated 8-shaped or double keyhole slot 20 which when engaged with the underside of the head 16 will freel rotate on the pin when the pin is in ei er of the enlar ed ends of the slot. The lever can be shifled upon the pin by turnin the lever to such position t at the para] el sides of the reduced portion are arranged parallel With the longitudinal axis of the slot. When the parallel sides of the reduced portion are at right angles to slot, the lever cannot hifted u on the pin, as will be readily understood. 'lelie forwa'rd end of the lever is provided with a yoke 21 which in certain positions of the ever is arran d to engage a stud 22 projecting vertica ly from the forward end 13 of the operating lever, while the rear end of the lever 19 is formed to rovide a handle 23 lying substantially para lel to the flange or stationary handle 8.

perspective view of the lever the longitudinal axis of the t In the casing'outit. which has been indicated at 24, I preferably provide a source of current in the form of a storage or dry battery 25, one terminal of -which may be connected by a cord to'one terminal of the electro-magnetsas at 26, and the opposite terminal may connected to one terminal of the make and break connections, as shown at 27. The terminals of the battery may also be connected and I may connect two ofthe terminals of the transformer T to the terminals 26 and 27. This transformer is preferably an ordinar bell transformer whose op osite termina s may be connected to 110-vo t circuit such as is used in house lighting and the machine is preferably 01perated through this source of power and t e battery only used where such power is `not availa le. Y

Intermediate the terminal 27 and the one contact 28 of the make and break contacts, I provide a switch, 29 in the form of a 'spring retracted plug, as shown in Figures 2 and 3, which when the machine is arranged to be operated electrically, lies in the path of the rear end 23 of the lever 19, so that upon moving the handleV toward the stationary handle 3 the plug switch will be operated to com lete the circuit from the terminal 27 to t e make and break contact 28. The opposite make and break contact 30 is referably groundedvl upon the plate 2 as is a so the last one of the magnets which are wired in series.

In the electrical o ration of the clippers the spring 14 holds t e rear end of the o eratinlg lever 8 against the contacts 28 an 30 so t at when t e manualoperatin lever is moved toward the stationary han le 3, the switch 29 completes the circuit as follows: terminal 27 ,switch 29, contact 28 lever 8 to contact 30, over the plate 2 to the electromagnets and from there over conduit 31 to terminal 26 and back to the battery or transformer. The circuit being thus completed and the magnets energized, the lever 8 forming the armature thereof is drawn toward the magnets against the tension of the spring 14. Immediately upon the lever being released from the contacts 28 and 30, the circuit is broken, and the magnets deenergized, permitting the spring to again return the armature to a point where it bridges the contacts 28 and 30, ,as will be readily understood. As long as the switch 29 isheld `to com lete the circuit `from the terminal 27 to e contact 28, this-reciprocation of the armature and the making and breaking of the circuit will continue and thus throw the forward end 13 of the lever reciprocating the cutter 9 over the cutter plate 1.

When it is desired to manually manipulate the clipper the lever 19 is turned upon the pivot pin 15 until the parallel sides of with the longitudinal axis of the slot 20 when the lever can be moved forward and the in engaged in the rearmost enlargement of t 4e slot, as is common in adlustable pliers. When this has been `done and the lever operated to carry the handle 23 toward the stationary handle 3, it will be seen that the rear end of the handle 23 is slightly forward of the switch 29 and the switch out of the path of the handle and also that the yoke 21 is in position to engage the stud 2.29, By moving the handle 23 toward the stationary handle 3, the lever 8 is operated similar. to the action of the ma ets, and by pping and releasing the han les 23 and 3 t e cutter plate 9 may be caused to reciprocate in a similar manner to the power reciprocation just described.-

I have described the magnets as being wired in series but I wish it to be clearliy understood that they may be wired in para lel or the maybe of varyin rvoltage capacities an one or more of t em used with the battery, while the remainder may be wired simply for use with the transformer, or the wiring may be independent of one of the magnets or any of them from the transformer and battery.

.What I claim is `1. A clipper comprising relatively movable cutter plates,y power operated means for a part of the operating lever to operate the same.

3. A clipper comprising relatively movable cutter plates, power operating plates for ,roducing relative movement including an electrical switch, an o erating lever and a manually operated member havin a shiftable enga ment with a ivot w ereby it may be se ectively engaged with a part on the operating lever or with the switch,

4. A clipper comprising relativel movable cutter plates, electrically contro led operating means for producin relative movement of the plates embo ying in part a pivoted operating lever and an electrical switch, ,and a manually o erated member pivoted and shiftable on t e pivot of the operating lever whereby it may be selectively engaged with a part on the operating lever or the electrical switch.

5. A clipper comprising relatively movable cutter plates, power operated means for producing relative movement of the plates including in part electrically operated mag# nets, an electrical switch and an operating lever, said operating lever being pivoted and s ring-pressed rn one direction, and a manua y operated member pivoted and shiftable on the pivot of the lever whereby it is adapted for selective enga ment with a part on Vthe lever or with t `e switch, said manually operated member adapted to move the lever against the tension of the s ring to produce relative movement of the ip ates. 6. In a. clipper, a fixed cutter p ate a movable cutter plate, la stationa handle, a pivoted lever for reciprocating t e movable cutter plate over the stationary cutter plate, electrical means including a switch for reciprocating said lever, a stud on the lever and a manually operated handle movable toward and away from the stationary handle and pivoted and shiftable on the pivot of the operating lever whereby it is arranged for `selective engagement with the stud or` 'the switch.

8. A clipper comprising relatively movable cutter lates, an operatin lever for producing re ative movement o the plates, power operated means associated with the operating lever and normally ino eratve, and manual operatin means shi table to actuate the operating ever or to render the power operated means o rative.
